摘要: 高能闪光X光照相在流体动力学实验研究中具有重要应用，作为一种产生多脉冲X光的重要手段，中美俄等国家的多脉冲直线感应加速器（LIA）技术方案各具特色。本文探索了一种百kV四脉冲产生技术，即利用数十kV的低气压伪火花开关驱动三同轴电缆Blumlein线产生单脉冲高压，数十kV的单脉冲高压经感应叠加器的电压叠加产生百kV的单脉冲高压，采用相同的四套脉冲高压发生器输出百kV的单脉冲高压，经同轴高压硅堆汇流器获得四脉冲高压输出。仿真和实验结果表明：该方案可以产生脉冲间隔可调的百余kV的四脉冲高压，且该高压发生器具有结构紧凑、可移动等特点，有望成为一种新型的可应用于多脉冲直线感应加速器中的脉冲功率源。

Abstract:Background High-energy flash X-ray photography has important applications in the hydrodynamic experiments. As an important means of generating multi-pulse X-ray, the technical scheme of multi-pulse linear induction accelerators (LIA) of each countries have their own characteristics.Purpose Based on requirements for the compactness, mobility, and high reliability of multi-pulse LIAs, the project team is exploring various novel multi-pulse power source technologies that can be used for multi-pulse LIAs.Methods In this paper, a 100 kV four-pulse generation technology is explored, that is, a low-pressure pseudo-spark switch of tens of kV is used to drive the Blumlein line of tri-coaxial cables to generate multi-pulse high voltage, and the multi-pulse high voltage of tens of kV is superimposed by an induction voltage adder to generate a multi-pulse high voltage of 100 kV. The same four sets of pulse high voltage generators are used to output multi-pulse high voltage of 100 kV, which are converged by a coaxial high-voltage diode to obtain four-pulse high voltage output of 100 kV.Results Simulation and experimental results show that the scheme could generate four-pulse high voltage of more than 100 kV with adjustable pulse interval.Conclusions This compact and movable 100 kV four-pulse high voltage generator is expected to become a new multi-pulse power source for multi-pulse LIAs. -
